Multi‐Level Street‐Based Analysis of the Urban Fabric: Developments for a Nationwide Taxonomy
Geographical Analysis, EarlyView.Multiple fabric assessment (MFA) is a computer‐aided procedure designed for identifying and characterizing urban fabric types (morphotypes) from a street‐based perspective. Nonetheless, the original MFA presents some limitations: it relies on surface‐based descriptors, conceived as proxy variables for the pedestrian perspective in urban form analysis ...

Remarks on τ$\tau$‐tilted versions of the second Brauer–Thrall conjecture
Bulletin of the London Mathematical Society, EarlyView.Abstract In this short note, we state a stable and a τ$\tau$‐reduced version of the second Brauer–Thrall conjecture. The former is a slight strengthening of a brick version of the second Brauer–Thrall conjecture raised by Mousavand and Schroll–Treffinger–Valdivieso.

On the isoperimetric Riemannian Penrose inequality
Communications on Pure and Applied Mathematics, Volume 78, Issue 5, Page 1042-1085, May 2025.Abstract We prove that the Riemannian Penrose inequality holds for asymptotically flat 3‐manifolds with nonnegative scalar curvature and connected horizon boundary, provided the optimal decay assumptions are met, which result in the ADM$\operatorname{ADM}$ mass being a well‐defined geometric invariant.

Continuous group cohomology with coefficients in locally analytic vectors of admissible $ \mathbb{Q}_p $-Banach space representations [PDF]
arXiv, 2023 We show that the continuous cohomology groups of a $ p $-adic reductive group with coefficients in the locally analytic vectors of an admissible $ \mathbb{Q}_p $-Banach space representation are homeomorphic to those with coefficients in the Banach space representation itself.

Periodic solutions of differential equations with periodic constraints
Mathematical Methods in the Applied Sciences, Volume 48, Issue 4, Page 5007-5015, 15 March 2025.We study the harmonic solutions of periodically perturbed differential equations subjected to a possibly time‐dependent constraint. We obtain a degree theoretic condition ensuring a “global branching” result for the nontrivial periodic solutions. The argument stems from a combination of techniques from the theory of topological degree and differential ...

Data‐driven nonlinear state observation for controlled systems: A kernel method and its analysis
The Canadian Journal of Chemical Engineering, Volume 103, Issue 3, Page 1122-1138, March 2025.Abstract This work proposes a data‐driven state observation algorithm for nonlinear dynamical systems, when the true state trajectory is not measurable and hence the states information needs to be reconstructed from input and output measurements. Such a reduction is formed by kernel canonical correlation analysis (KCCA), which (i) implicitly maps the ...

An Extension of Tychonoffs Fixed Point Theorem to Quasi-point Separable Topological Vector Spaces [PDF]
arXiv, 2020 In this paper, we introduce the concepts of m-quasiconvex, originally m-quasiconvex,and generalized m-quasiconvex functionals on topological vector spaces. Then we extend the concept of point separable topological vector spaces (by the topological dual spaces) to quasi-point separable topological vector spaces by families of generalized m-quasiconvex ...

Communications on Pure and Applied Mathematics, Volume 78, Issue 3, Page 545-591, March 2025.Abstract While there are numerous results on minimizers or stable solutions of the Bernoulli problem proving regularity of the free boundary and analyzing singularities, much less is known about critical points of the corresponding energy. Saddle points of the energy (or of closely related energies) and solutions of the corresponding time‐dependent ...

An Extension of Tychonoff Fixed Point Theorem [PDF]
arXiv, 2019 In this paper, we introduce the concepts of weaknorm, quasi-weaknorm on real vector spaces. By these concepts, we introduce the concept of quasi-locally convex topological vector spaces, which include locally convex topological vector spaces as special cases.
